The one-loop corrections to baryon magnetic moments from the Feynman diagrams depicted in Fig. REF  have a nonanalytic dependence on the quark mass of the form \(m_q \ln m_q\) . The computation of these diagrams requires a rather formidable effort to reduce the operator structures involved. In Refs. [1]}, [2]}, relative corrections to order \(1/N_c^4\)  in the \(1/N_c\)  expansion were included. The incorporation of all the structures present for \(N_c=3\)  needs the inclusion of relative terms of up to order \(1/N_c^6\) . Again, a great deal of computational ease is gained by using some of the operator structures already reduced in the renormalized baryon axial current computed in Ref. [3]}. Other structures appear for the first time and need be reduced.
